.ua

.ua is the Internet country code top-level domain (ccTLD) for Ukraine. To register at the second-level (example) domainname.ua, possession of the exact trademark (matching the domain name) is required. It is not required for third-level domains (.com.ua, .net.ua, etc.).

Statistics
As of March 2017, around 10.78% of all the .ua domains were served via secured HTTPS protocol, with the Let's Encrypt Authority X3 being the most popular SSL certificate. Nginx is the most popular web server, serving 68.97% of the .ua domains, followed by Apache serving 17.75% of the total .ua domains.
Third-level & second-level domains
To remove the risk of cyber squatting, registration of second-level domains directly below .ua is restricted to owners of registered trade marks, who may register a domain name similar to that of the trade mark in question. However, third-level domains can be registered beneath some of the following:
.com.ua: paid, commercial organizations
.edu.ua: free, available only to proved educational organisations.
.gov.ua: free, available only to governmental organizations
.net.ua: paid, network service providers
.in.ua: paid, domains for individuals
.org.ua: paid, other organizations (non-commercial)
.mil.ua: free, available only to armed forces
.dod.ua
There are also second-level domains which are region-specific. These are less popular than the above list (making domain names more available) but they are sometimes restricted to organisations exclusively from within the region.
